摘要：

With the help of software Fine/Design 3D and a computational fluid dynamics (CFD) method, the optimization design of a three-dimensional blade was carried out for fan/compressor. Then three-dimensional numerical simulation software named Fine/Turbo was used to calculate typical working conditions of both the new fan/compressor and the initial one at design rotating speed. The flow field performance under design speed condition was obtained. Numerical results show that efficiency is increased by 1.05% at design point after optimization of fan blade, without changing the stage total pressure ratio. The optimization obviously improves, especially in the fan stream, the flow structure and parameters of the fan/compressor's main flow.
